Which component must be backed off to allow the propeller to be pulled off the shaft?

Explanation:
The propeller is held onto the shaft by a retaining nut, which clamps the prop hub onto the shaft. To pull the prop off, back off that retaining nut enough to relieve the axial clamp so the hub can slide away from the shaft. The other parts—snap ring, spacer, and front cone—serve alignment or spacing or locking purposes, but they are not the component you back off to remove the prop.
